Alien Blitz updated

Misc small changes (website url on title screen, forgot to credit gperfection² icons…)

I finally have a Samsung device (GS3) to test my games on it, so I corrected some of the zooming glitches (not a big issue, just zooming triggers when it shouldn’t in the menus).
I like this device, it’s a lot quicker to transfer apk through USB and load maps on it than on any other device I have. The strange thing is that my game is yellowish, it’s kinda weird as it’s the first time I see this, I guess the screen is a bit different.
